2 Claims.

This invention relates to a means for stamping or printing and preparingrubber goods 0r articles such as balloons, finger cots, and similararticles for packing or shipment, and has for one of its objects theproduction of a simple and eflicient means for stamping or printing atrade-mark or other indicia upon the goods or articles and treating thesame in a manner whereby the stamped or printed subject matter will notblur or rub while a bead is being rolled orformed upon the article.

A further object of this invention is the production of a simple andefficient means for rolling a bead upon rubber goods or articles such asballoons, finger cots, and the like, by rolling a bead upon itself fromthe lower portion of the article, through the medium of a lateralpressure frictional contact movable element to assure an economical andaccurate operation in the rolling of the bead, as Well as the removal ofthe article from its supporting form after the bead has been formed.

Other objects and advantages of the present invention will appearthroughout the following specication and claims.

In the drawings:

Figure l is a top plan View of my device;

Figure 2 is a side elevational view, certain parts being shown insection, and the supporting forms being broken away;

Figure 3 is a side elevation of my device, looking at an opposite sidefrom that as shown in Figure 2, certain parts being shown in section;

Figure 4 is a vertical sectional View through a portion of the dial orrotating table, one of the forms being shown in section and the printingapparatus being shown in side elevation;

Figure 5 is a transverse sectional view taken on line 5--5 of Figure 4.

By referring to the drawings, it will be seen that Ill designates asupport which is preferably of a hollow box-like structure. A verticallyextending power shaft II is supported by the base, and carries a powerwheel I2 over which passes a suitable driving belt I3, which belt I3 maybe driven from any suitable source of power. This power shaft I Icarries a frictional driving disc I4 at its upper end above the supportIll of which frictional driving disc I4 is fitted the dial or rotatingtable I5, the disc I4 fitting within the cavity I 6 of the dial orrotating table I5, as shown in Figure 4. The dial or table I5 is securedin position through the medium of an anchoring screw I'l, which screwI'I extends through a suitable spring washer I8 and is threaded into theupper end of the power shaft II,y as shown in Figure 4. The tension ofthe frictional contact between the dial I5 and the driving disc I4 maybe regulated, of course, by the adjustment of the screw I1 to provide aproper frictional drive for the dial I5 and permit the dial I5 to bestopped periodically as will be hereinafter described.

'Ihe dial or rotatingtable I5 preferably com prises four radiating armsI 9 and each arm I9 supports a vertically extending form 20 in the 10nature of a hollow tubular member tapering slightly toward its upper endand having a longitudinally extending passage 2| through its centerextending from end to end and communicating with a vertically extendinghollow tubular jour- 15 nal 22,`the hollow tubular journal 22 beingfitted into the lower end of the form 20, in a manner as shownY inFigure 4. vThe lower end of the tubular journal.22 in each instanceextends through` an aperture 23 formed in the arm I9, 20 as shown inFigure 4, in this way efciently supporting `the fo1'm'2ll-for rotation.The lower end of the form 20 preferably'ca-rries a reinforcing metalband 24, the form 20 being preferably formed of wood. The outer end ofeach form 20 25 is rounded, as indicated at 25, and a pluralityofradiating and longitudinally extendingv channels 26 are formed in theouterface of the form 20 in each instance, so as to provide air escapechannels leading to the central opening or bore 2I, 30 thereby allowingair to escape through the upper end of the form 20 as the bead 2'I ofthe Arubber article 28 is being rolled in the manner hereinafterdescribed.

One of the purposes of 'the-present invention is 35 to facilitate theprinting of a trade-mark or other indicia upon the rubber article 28which is of a film-like rubber structure closed vat its upper end andopen at its bottom end, and which is adapted to be placed over the form20 to fit upon the form in the'manner shown in Figure 3. The dial I5willvbe rotated through the medium of the friction drive previouslydescribed causing the dial I5 to travel in the direction of the arrowsindicated in Figure 1. 45

'In actual operation, it has been found practical for an opera-tor tomanuallyfplace the rubber article 28 over one of the forms 2U, as oneform passes the position of the operator, and it has been foundpreferable to have the dial I5 remain 50 k at rest while the article 28is placed over the form 2li. For this'purpose, I provide a stop key inthe nature of a U-shaped member 29 having vertically extending ngers 3i!and 3l extending through the top of the base i0, as shown in Fig- 55 ure3. 'I'he finger 30 carries a knob 32 at its upper end and a coil spring33 which is interposed between the knob 32 and the upper face of thebase I0. The nger 3l is adapted to normally lie in the path of travel ofthe lower ends 22a of the tubular journals 22 which depend below thedial I5. This linger 3l will cause one of the forms 28 to stop in aproper position in front of the operator as the dial I5 rotates in thedirection of ,the arrows shown in Figure 1 due to the fact that thedepending end 22a will abut against the upper end of the finger 3I Whenthe operator has properly placed the rubber article 28 over the form 20,the dial I5 may be released by the operator merely pressing the knob 32downwardly out of contact with the depending end 22a-note Figure 3,whereupon the friction drive will cause the table or dial l5 to continuein its movement. In this way, the table or dial I5 will intermittentlyrotate for each quarter turn, coming to rest at each quarter of a turnand will be manually released by depressing the stop key 29.

A printing mechanism A is carried by the support Ill in the path ofmovement of the forms 2U, and at a position intermediate two of theforms when the dial I5 is at rest. This printing mechanism comprises avertically extending frame 34 which is carried by the support I in anysuitable or desired manner upon the upper end of which is pivotally hunga stamp supporting arm 35, and a pad supporting arm 36 in proper spacedrelation and in the manner as shown in Figures 3 and '4. A iiat spring31 is carried by the frame 34 and engages the arm 35 normally forcingthe arm 35 inwardly and a flat spring 38 is carried by the offset sideof the frame 34 and engages the arm 36 for forcing the arm 36 inwardlyto cause the stamp 39 carried near the lower end of the arm 35 tonormally contact with the inking pad 4i) carried by the lower end of thearm 36. The stamp 39 and also the pad 48 are located in a position uponthe arms 35 and 36 so as to preferably stamp the article 28 near itslower open end as will be obvious by considering Figures 3 and 4.

The arm 35 is provided with a shoe 4| at its lower end having a convexinner face 42. The arm 36 is provided with a shoe 43 at its lower endhaving a convex inner face 44 the convex faces 42 and 44 facing towardeach other and when the stamp 39 and pad40 are in contact, the ends ofthe respeotiive shoes 4I and 43 will provide a flaring opening in thedirection of the entering form 28 as it passes in the direction of thearrows shown in Figure 1, and as the form 20 passes in the direction ofthe arrows shown in Figure 1, the base of the form 20 will contact withthe convex faces 42 and 44 of the shoes 4I and 43 in the manner shown inFigures 4 and 5 and force the lower ends of the arms 35 and 36 from theposition shown in Figure 3 to the position shown in Figures 4 and 5. Theshoe 43 is of suicient size to move the arm 36 to a position whereby theinking pad 48 will be out of contact with the article 28 as the form 29carrying the article passes between the arms 35 and 36. The article 28carried by the form 20 as it passes the printing pad 39, however, willmerely roatate by, and in contact with, the stamp as the dial I isrotated, thereby causing a clear and distinct impression of the stamp toappear upon the article 28 as the form rolls across the face of thestamp. As soon as the form 26 carrying the article 28 which has beenprinted, passes from between the arms 35 and 36 the springs 31 and 38will force the stamp 39 in contact with the pad 48 through the swingingof the arms from the position shown in Figure 4 to the position shown inFigure 3. re-inking the stamp, and at the same time because of the closecontact provided, seal the face of the pad to prevent the pad frombecoming dried out. This action will add greatly to the life of the padas well as to the life of the stamp.

It is quite important in an operation of this character that the ink ofthe stamped impression upon the article 28 be treated in a manner so asto prevent it from smearing as the lower end of the article is rolled ina subsequent step. For this reason, I provide a special dusting mediumfor applying starch, talcum powder, or any other similar material whichwill efficiently dry the inl: which has been stamped upon the article28. To accomplish this result, I have provided a special dustingmechanism B, as shown in Figures 1 and 2, located in close proximity tothe frame A. This dusting mechanism preferably comprises a frame 45which supports an endless conveyor belt 46 in a manner shown in Figures1 and 2, which endless conveyor belt is driven from a verticallyextending shaft 41. The shaft 41 is driven'by means of the belt 51. Theconveyor ybelt 46 extends in the direction of the path of movement ofthe forms 20. The frame 45 is preferably supported upon a hollowstandard 48 carried -by the base l0 in the manner shown in Figure 2 forswinging movement toward and away from the center of the dial I5, as isindicated in dotted lines in Figure 1 and this frame 45 is provided witha projecting arm 49 which arm 49 is engaged by a coil spring 5U anchoredat its opposite endv to a post 5I carried by the base I0. This` spring5I] normally yieldably holds the conveyor belt 46 in contact with thearticle 28 carried by one of the forms 20 as it passes the belt 46. Asone of the forms 20 carrying the article 28 passes in the direction ofthe arrows shown in Figure 1 and moves to the position shown in dottedlines in Figure 1, the frame 45 will be swung to the position shown indotted lines in Figure 1 where the conveyor belt 46 will contact with adustingroller 52 mounted within a dusting cabinet 53 supported upon thebase I0 in a proper position for contact with the belt 46. This dustingroller 52 may be driven by a belt 54 through the medium of a pulley 55carried by the shaft 56. As the dial I5 travels in the direction of thearrows shown in Figure 1, the frictional contact of the outer face ofthe article 28 carried by the form 20 by rolling over the belt 46 willcause the article 28 to be thoroughly dusted and the printed subjectmatter properly treated for preventing smearing. The belt 46 is driventhrough the medium of the shaft 41, which shaft 41 is in turn driventhrough the medium of the belt 51, the belt 51 being driven by a pulley58 carried by the shaft 56.

Through this operation, the conveyor belt 46 will be periodicallyengaged by one article, such as the article 28, carried by one of theforms 20 for properly dusting, and this movement will swing the frame 45carrying the belt 46 into contact with the dusting roller 52, therebyperiodically renewing the dusting of the conveyor belt 46.

After having stamped and then dried the article, the next step necessaryfor properly handling the article is the removal of the article from theform such as the form 28. I, therefore, have provided a speciallyconstructed removing device C which is preferably located in spacedrelation from the dusting device and in the path of movement of theforms 28 as they are moved'through the rotation of the dial. Theprinting device A is preferably located at a point between the first andsecond quarter turns, the dusting device B being located at a pointapproximately the beginning of the third quarter turn. It should beunderstood, however, that the exact location of the printing, dustingand removing devicesmay be varied Without departing from the spirit ofthe invention, the locations at present illustrated having been found tobe an eiicient arrangement for speedy `operation, accurate timing, andeflicient manipulation. In order to facilitate the removal of thearticle 28 from the form 28, and the formation or rolling of the bead21, I provide a vertically extending conveyor belt supporting frame 59which extends vertically of the base I8, the lower end of the frame 59being journaled upon the shaft 56 and being provided with a dependingarm 68 which engages a spring 6I. The spring 6I is anchored upon thebase I8, as at 62, and normally swings the frame 58 in the direction ofthe forms 28 carried by the dial I5. The shaft 56 is driven through themedium of a belt 63, the belt 63 passing over a pulley 64 carried by thepower.

shaft il.

The conveyor belt frame 59 carries a vertically operating conveyor belt65 which passes over a lower pulley 66 and an upper pulley 61, the upperpulley 61 being located adjacent the upper end 68 of the verticalreceiving bin 69 carried by the base I8. The conveyor belt 65 is placedin a position between the dial I5 and the bin 69 as shown in Figure 3.The spring 6I will frictionally hold the belt 65 at a tension infrictional wiping contact to prove lateral pressure frictional contactupon the lower end of the article 28, thereby causing the bead 21 to berolled upwardly in the direction of the arrows shown in Figure 3 untilthe bead 21 has taken the position shown in Figure 3, the channels 26permitting the escape of air and preventing the compression of air underthe outer end of the article 28 due to the fact that the air may passthrough the channels 26 down through the bore 2I and out through thelower end of the tube 22.

The frame 59 is provided with an overhanging end 18 which overhangs thepath of movement of the forms 28 as they pass while the dial I5 isrotating. The outer extremity of the overhanging end 18 supports a wheel1I which is provided with a plurality of flexible blades or ngers 12preferably formed of rubber and this wheel 1I is driven through themedium of a cross belt 13 from a shaft 14 carried by the pulley 61, thewheel 1I traveling in the direction of the arrows. As the article 28reaches the upper end of the form 28, as shown in Figure 3, theresilient or flexible finger 12 will contact with the article 28 andshift the same off the upper end of the form 28, the inner edge of thebead 21 being engaged by the upper end of the conveyor belt 65 causingthe article 28 to ride over the upper end of the conveyor belt in themanner shown in dotted lines in Figure 3, and be deposited into thereceptacle or bin 69.

Through the medium of the present machine, the operations of stamping arubber article, and rolling a bead from the bottom edge, are greatlyfacilitated, and the time involved is shortened. Furthermore, thepresent machine provides a compact arrangement, the various elements ofwhich may be closely arranged and need not be spaced at great distanceto provide time for drying between the time of stamping and the time ofrolling the bead. The dusting of thev wet stamped indicia through themedium of the dusting belt 46 cuts down the time and distance ofoperation, eliminating the usual long con- Veyor belt system andpermitting the various parts performing the various steps of operationto be closely arranged in compact relation and thereby providesl aneconomically operated machine occupying a minimum amount of space.

The method employed in the operation of my device is as follows- Theoperator will stand in front of the machine adjacent the actuating knob32 and will manually slip one of the articles 28 over the upper end ofone of the forms 28, and then release the dial I5 by pressing the knob32 downwardly whereupon the frictional driving will cause the dial i5 torotate in the direction of the arrows shown in Figure 1, causing theform upon which the article 28 has been placed to force its way betweenthe shoes 4I rand 43 spreading the arms 35 and 36 apart and causing thelower end of the rubber article 28 to roll across the face of the stamp39. This will cause an impression from the stamp to be printed upon theouter face of the article 28 adjacent the stamp, and because of thestructure of the shoe 44 the pad 48 will be held out of contact with thearticle 28 as is shown in Figure 5. After the article 28 carried by theform 28 has moved beyond the stamp, the arms 35 and 36 will be swungtoward each other at their lower ends, the shoes 4I and 43 overlappingand allowing the stamp 39 to snugly contact with the pad 48 therebyre-inking the stamp and making it ready for the next operation.

After the form 28 which carries .the article 28 has passed `through theprinting device A, it

next contacts with the endless conveyor belt 46 which travels in ahorizontal direction and is located in alignment with the printed orstamped indicia of the article 28, and the continued movement of theform 28 which carries the article 28 causes the frame 45 to be swung tothe position shown indotted lines in Figure 1 where the conveyor beltwill contact with the dusting roller 52.

As the form 28 which carries the article 28 moves to a third position,the lower edge of the article 28 is gripped by the lateral frictionmoving contact of the vertically traveling conveyor 65 for rolling thebead 21 vertically on the form 28, where the rolled article 28 is thenkicked oi and conveyed into the bin or receptacle.

It should be understood that the various parts are properely timed tooperate in sequence, and that the freely rotatable forms 28 may roll inproper timed relation over the face of th printing stamp 39 as well asthe dusting belt 46 to insure a clear and clean-cut impression.

It should be further understood that certain detail changes in themechanical construction,

combination, and arrangement of parts may be employed without departingfrom the spirit of the invention, so long as such changes fall withinthe scope of the appended claims.

Having described the invention, what I claim as new is:

l. In an apparatus of the class described, a support, a rotating dial, aplurality of upstanding forms carried by the dial and arranged on theradius of a circle, a printing frame arranged in the path of movement ofthe forms, a stamp carrying arm pivotally suspended within the frame andadapted to print indicia upon an article carried by the form as the formmoves by the stamp, means for re-inking the stamp, and inwardlyextending convex feet carried by the printing frame and the means forre-inking the stamp, the forms being adapted to pass between the convexfeet for forcibly separating the feet, thereby separating the printingframe and the means for re-inking the stamp as the forms passtherebetween.
